  • Maybe this is due to my flake setup, but the way I currently update (nix flake update, then nixos-rebuild) I can only update everything at once. At times, this can feel clunky compared to e.g. arch which lets me update individual packages. Do you have any suggestions on how to do partial updates?

    Especially in a middle school math/physics setting, I would expect reasonable units. Otherwise, how would kids understand the relationship between force and acceleration? Do you use mile / hour / min for the acceleration due to gravity as well? Do you have a funky replacement for Newton too?

    That’s not the problem. Coming from metric, I expected m s-2 for acceleration. The imperial units for distances are weird enough in their own right – but using two different units of time for the two time derivatives is truly unholy.

    The natural representation would be the transient solution u(t) or i(t). Harmonic solutions are merely a special case, for which it turned out complex numbers were useful (because of the way they can represent rotation). They certainly serve a purpose there, but imo this is not an instance of ‘complex numbers appearing in nature’.
